BUTTON.

SPECIFICATION forming part of Letters Patent No. 326,992, datedSeptember 29, 1885.

Application led May 29, 1885.

To all whom t may concern.-

Be it known that l, EDMoND KUHN, of Brooklyn. county of Kings, and Stateof New York. have invented an Improved Sleeve- Button. of which thefollowing` is a specilication, reference being had to the accompanyingdrawings, in which- Figure 1 is a side view of' my improved button. Fig.2 is a vertical central section of the saine, showing the head and shoein their normal positions. Fig. 3 is a similar section thereof, showingthe head and shoe separated from each other. Fig. 4 is a horizontalsection of the same on the line c c, Fig. 2, looking toward the head ofthe button.

This invention relates to that class ot' buttons in which the head isseparable from the shoe.

The object of this invention is to produce a simple separable button, inwhich the devices t'or holding its parts together are not easily brokenor deranged, and which are in` closed within it, so that in externalappearance it resembles a common cuff-button.

In the drawings, A represents that part of the post which is carried bythe shoe B, and D represents that part of the post which is carried bythe head E.

The post A is composed of an inner tube, m, that projects from the shoeB, and also of an outer tube, n, that surrounds the tube m, and issoldered or otherwise rigidly secured thereto. The inner tube, m, of thepost A is provided at its upper end with two bayonetslots, a, which areopposite each other. Each of these two bayonet-slots a has a verticaldownwardly-extending part, e, which is open at the upper end, ahorizontal part, f, and a short vertical upwardly-extending part, g. Thetube a covers the slots a, thus hiding them from view and preventingtheir edges from cutting the cuffs.

The post D is provided with two outwardly projecting pins, h, which areopposite each other. The pins l1. are adapted to be pressed downward inthe vertical portions e of the slet; a against the action of a spring,cl, which is contained within the hollow post A until said pins arealigned within the horizontal portions f of said slots a, when, onturning the head E and post D they are moved horizontally in the parts funtil said pins come in line Withthe vertical upwardly-extendingportions g of said slots. Then the pins h (No model.)

reach this point, the spring d being free to expand, presses the pins hup in said portions g of the slots a. and holds them there.

The head E ofthe button consists of an upper face-plate, t', which hasa. downwardlyextending rim,j. Opposite the face-plate t' is attached tosaid rim a circular lower plate, Z. The lower plate. Z. has a centralopening for the admission of' the post A, which enters said opening whenthe button is complete, as shown in Fig. 2. ln the head E, between thefaceplate t and the lower plate, Z, is placed a springdatch, F, thatbears upon the upper end of the post A, and thereby prevents thepressure of the arm ofthe wearer of the button from overcoming theresistance of the spring Zand fromcrowdingthepinshinthe portions g of'the slots a back into the portions f. This spring-latch F may be movedout of the Way of the post A by taking hold of its outer end, whichextends beyond the periphery of the head E, as is shown in Fig. 4, therim] being perforated for this purpose.

After the latch is moved away from the post A, as shown by dotted linesin Fig. 4, so that the inner end of the post A may be moved toward theface-plate t', the head and shoe can be pressed toward each other untilthe pins h come in line with the horizontal grooves f, whereupon thehead is turned to bring said pins in line with the upright slots e. Thespring d then forces the head and shoe wholly apart.

It will be seen that the post A requires no projection of any kindforabutting against the spring-latch F, as the upper end of the 'postitselfI answers this purpose, nor are the slots a exposed. rlhus abutton is produced that has no external projections except the end ofthe spring-latch F.

l claim- The hollow head E, post D, and pins h, coinbined with thespring latch F, contained within said hollow head E, and with the hollowpost A that fits the central aperture of the lower plate, l, of saidhollow head, said post A having bayonet-slots a, concealed by the tuben, and the shoe B and spring d, substantially as herein shown anddescribed.
